Yini eholwa?
I-LED imele "ukukhanya okukhinyayo." Kuyithuluzi le-semiconductor elikhipha ukukhanya lapho kudlula lapho kudlula khona lapho kudlula khona. Ama-LED asetshenziswa ezinhlobonhlobo zezicelo, kufaka phakathi ukukhanyisa, ukuboniswa, izinkomba, nokuningi. Baziwa ngokusebenza kwabo kwamandla, ukuqina, kanye nesikhathi eside sokuphila isikhathi eside kuqhathaniswa nama-ancorescent yendabuko noma ama-fluorescent. I-LEDS iza ngemibala ehlukahlukene futhi ingasetshenziswa emikhiqizweni ehlukahlukene ehlukahlukene, kusuka kumalambu wenkomba alula ukuze aboniswe ama-elekthronikhi anezinhlelo zokusebenza nokukhanyisa.
Umgomo wokukhanya kwe-LED
Lapho ama-elektroni kanye nezimbobo emhlanganweni we-PN we-ding emfishini ekhanyayo ihlangana kabusha, ukuguqulwa kwama-elektroni kusuka ezingeni eliphakeme lamandla ezingeni lamandla aphansi, futhi ama-elektroni akhipha amandla aphezulu ngendlela ye-photons ekhishwe (amagagasi e-electromagnetic), okuholela i-electrollorinence. Umbala wokukhanya uhlobene nezinto ezibonakalayo ezakha isisekelo sazo. Izinto eziphambili ezikhona njenge-Gallium Arsenide Diode zikhipha ukukhanya okubomvu, i-gallium phosphide diode ikhipha ukukhanya okuluhlaza, i-silicon carbide diode ikhipha ukukhanya okuphuzi, kanye ne-gallium nitride diode ekhipha ukukhanya okuluhlaza okwesibhakabhaka.
Ukuqhathaniswa komthombo okhanyayo
I-LED: I-High Electle-Optical Conversion Ecerliancen (Cishe i-60%), eluhlaza kanye nemvelo enobungani, ifinyelela emahoreni angama-100,000), akukho voltage ephansi (cishe i-3V), akukho ukulahleka kokuphila ngemuva kokushintsha okuphindaphindwayo, isizukulwane esishisayo , ukugqama okuphezulu, okuqinile futhi okuhlala isikhathi eside, kulula ukufiphala, imibala ehlukahlukene, imibala egxilile futhi ezinzile, akukho ukubambezeleka kokuqalisa.
Isibani se-Incandescent: Ukuguqulwa kwe-electro-optical okuphansi (cishe nge-10%), impilo emfushane (cishe amahora angama-1000), izinga lokushisa eliphakeme, umbala owodwa kanye nokushisa kombala okuphansi.
Izibani ze-Fluorescent: Ukuguqulwa kwe-Electro-Optical Conversion (cishe nge-30%), kuyingozi emvelweni (equkethe izinto eziyingozi njenge-mercury, cishe i-3.5-5mg / iyunithi), ukugqama kwe-ultraviolet, I-Flickrering Penomenon, ukuqala kancane kancane, inani lentengo ye-Rare Earth Izinto zokwakha, ukushintsha okuphindaphindwayo kuthinta impilo yesikhathi sokuphila, futhi ivolumu likhona Amalambu wokukhipha ama-Great.High-Presungressuregesing ephepheni: Sebenzisa amandla amaningi, awaphephile ongawasebenzisa, abe nesikhathi sokuphila esifushane, futhi abe nezinkinga zokunciphisa ukushisa. Zisetshenziselwa kakhulu ukukhanyisa kwangaphandle.
Izinzuzo ze-LED
I-LED iyi-chip encane kakhulu efakwe ku-epoxy resin, ngakho-ke incane futhi ingasindi. Ngokuvamile, i-voltage esebenzayo ye-LED ingu-2-3.6V, okusebenzayo kwamanje yi-0.02-0.03a, futhi ukusetshenziswa kwamandla akuphezulu kakhulu kune
I-0.1w. Ngaphansi kwezimo eziqinile futhi ezifanelekile kanye nezimo zokusebenza kwamanje, impilo yensiza yama-LED ingaba ngamahora angama-100,000.
I-LED isebenzisa ubuchwepheshe obandayo be-luminescence, ekhiqiza ukushisa okuphansi kakhulu kunokulungiswa okujwayelekile kokukhanyisa amandla afanayo. Ama-LED enziwe ngezinto ezingezona ezinobuthi, ngokungafani namalambu we-fluorescent aqukethe i-mercury, engadala ukungcoliswa. Ngasikhathi sinye, ama-LED nawo angaphinde asetshenziswe futhi asetshenziswe kabusha.
Ukusetshenziswa kwe-LED
Njengoba ubuchwepheshe be-LED buqhubeka buvuthwa futhi bakhule ngokushesha, izinhlelo zokusebenza ezengeziwe eziholwayo zivela ezimpilweni zethu zansuku zonke. Ama-LED asetshenziswa kabanzi ekubonisweni kwe-LED, amalambu omgwaqo, amalambu ezimoto, imithombo yokukhanyisa, imihlobiso yokukhanyisa, izibani zesikrini se-LCD, njll.
Ukwakhiwa kwe-LED
I-LED iyi-chip ekhipha ukukhanya, ubakaki nezintambo ezihlanganisiwe e-epoxy resin. Kukhanya, okungelona ubuthi futhi kunokwemelana kahle. I-LED inendlela yokusebenzisa indlela eyodwa, futhi lapho amandla aguqukayo aphezulu kakhulu, kuzodala ukwephulwa kwe-LED. Isakhiwo sokwakhiwa esiyinhloko sikhonjiswa esithombeni:
